เกจวัดแรงดันออกซิเจน has constructed its bovine animal competence heart in Badbergen, Lower Saxony. The cuts of beef are vacuum-packed in thermoforming and shrink-wrap machines, a process that has become extra efficient than ever following renovations at the website: Now, energy-saving Atlas Copco variable-speed vacuum pumps are used to create vacuum circumstances at two central stations.What used to be a combined slaughterhouse has become a “bovine animal competence center”: For many years, cattle and pigs had been slaughtered and butchered at the same time in Badbergen on behalf of different companies. In 2017, the Tönnies Group took over the location and decided to base its whole slaughtering operation in Badbergen – up till that time, this had taken place on the company’s main web site in Rheda-Wiedenbrück. In 2020, Tönnies Beef reopened the site after intensive conversion and renovation. The Group invested around eighty five million euro within the building and state-of-the-art expertise at this web site in a small city in northern Lower Saxony, between Oldenburg and Osnabrück. The slaughtering, butchering and finishing processes are based mostly on the newest cooling technology, machine-based butchering and highly automated selecting and delivery traces.
Several hundred tons of meat go away the positioning every day and 95% of the animal – practically every thing – is utilized. This permits Tönnies to fulfill totally different eating habits around the globe: While German shoppers choose lean beef, meat with a thick layer of fats is well-liked in Scandinavia and other European nations, in accordance with the manufacturer’s website.
Efficient screw vacuum pumps present forming, low and fantastic vacuums
“The cuts weigh between 1.5 and 9 kilograms after butchering,” explains Waldemar Metzger, Technical Manager of Tönnies Beef GmbH & Co. KG in Badbergen. The cuts are vacuum-packed for various major prospects. For this purpose, Tönnies has put in several packaging lines in the halls: Seven thermoforming roller machines and two robot-operated shrink-wrap packaging machines. Efficient Atlas Copco vacuum pumps are used in the methods to vacuum pack the tubular/shrink baggage and thermoformed plastic trays, and to keep the meat really contemporary. They work in two stations and provide forming, low and fine vacuums.
The thermoforming machines supplied by vacuum station 1. There are four Atlas Copco GHS 585 VSD+ variable-speed, oil-injected screw vacuum pumps that evacuate the air up to forty mbar (absolute), as properly as four small boosters that decrease the strain even additional to three mbar. One of the screw pumps provides the forming vacuum for the thermoforming curler machines, which only require around a hundred to one hundred fifty mbar for the forming course of. The different vacuum pumps on this station are connected to the boosters. One of the pumps is redundant at any given time: This is also the case in the second vacuum station, which includes 5 GHS 730 VSD+ pumps that remove the air from the shrink baggage at the Cryovac strains. “The dimension of the cuts of meat is routinely detected by our systems,” explains Waldemar Metzger. “The packaging machines then routinely insert the cuts of meat into the tubular baggage, which are cut to the right measurement beneath a vacuum bell.” Under the hood, all ambient air is then evacuated in two stages till the strain is round three mbar (fine vacuum).
“With the forming vacuum – or thermoforming vacuum, as it’s additionally known as – the plastic tray is shaped by cutting the foil roll,” says the Technical Manager. After filling the shell with smaller pieces of meat, the shell is “wed” to the cover movie: The tool closes and seals the packaging airtight at 3 to 5 mbar using the fine vacuum. Sorting machines assign the person trays and tubular luggage to larger boxes, which are then used to select customized boxes for buyer orders.
Efficient speed regulation reduces energy requirements by a third or more
Waldemar Metzger has been working in Badbergen for 20 years and has been part of the planning and execution stages of converting the mixed slaughterhouse to a purely beef operation from the very beginning. This included the decision to buy Atlas Copco variable-speed vacuum pumps. “As far as technology is concerned, being ready to differ the speed of the GHS vacuum pumps is important to us and saves power,” stresses the Tönnies employee. “Compared to fixed-speed machines, you possibly can reliably minimize down vitality necessities by round a third – maybe even by half, relying on the diversity issue.”
The controls on the vacuum pumps have a user-friendly plain textual content show, which also indicates the working hours and maintenance intervals. Since the Atlas Copco pumps could be connected directly to an exhaust system, it was attainable to make use of air-cooled pumps. According to the producer, this improves the climate of the room; it is now not necessary to have the additional room cooling typically required when using central vacuum techniques.
The project was applied on website by and with Oliver Hornberg, Managing Director of Eugen Theis Vakuumtechnik in Werther. He delivered the pumps to Tönnies Beef, ready to use – including a 400 m pipeline within the transformed slaughterhouse, measuring in locations to a diameter of DN 300. His company, Eugen Theis GmbH, was based in 1984 and specializes in vacuum technology. In 1999, Hornberg took over the business from its founder, Eugen Theis, and 20 years later, in late 2021, sold it to Atlas Copco after he could not discover a successor. “Our two youngsters are pursuing different career paths,” he says. Hornberg himself remains Managing Director even after the company was bought to Atlas Copco and is trying ahead to significant progress under the umbrella of one of the world’s largest suppliers of vacuum pumps. The company already operates all through Germany: “From Flensburg within the north to Regensburg within the south and Halle (Saale) within the east,” he says, outlining the attain of his firm: This additionally includes Badbergen in the (north)west, as he sometimes stops by at Tönnies Beef to maintain up the machines.
